Has anyone installed the Power Pump fuel pump?

[Chris 16409]

Brand X - The top is not stainless, rather claimed to be "rust resistant". Assume plated steel. The fuel lines are clamped directly to the (stainless?) steel lines rather than using the quick-connect barb fittings that the lines are designed to utilize.

I did the magnet test on the metal parts. I used a neodymium magnet since they are strong. The magnet stuck to the top of the pump but not to the metal fuel tubes.

right now I'm restoring a DeLorean with automatic transmission
the owner of this car buy some products from specialtauto without consulting me first.
in the past I have had personal conflicts with john hervey and even accuse me of thief without any evidence.
and for several years did not sell parts to Puerto Rico.
trust me I do not need specialtauto and low quality parts.
I'll give you an example:

gas pump is identical herko brand and is located in Florida and using ebay to sell at low prices
This is the Herko company ebay link: http://www.ebay.com/usr/e-herko?_trksid=p2047675.l2559
the pump is used for suburban and yukon 2002-2004 the model is herko 131ge for only $52 dollars
this is the link of ebay: http://www.ebay.com/itm/New-Premium-...NW6YiF&vxp=mtr

Picture 020.jpgPicture 011.jpgPicture 016.jpgPicture 017.jpgPicture 018.jpgPicture 019.jpg

pump pressure barely reaches 65 psi, the metal cap of the pump is not stainless steel
only has rustproofing.
the rubber seal is not used in the auto industry, It is used as a seal for outdoor lamps
to make them moisture-proof.
you can clearly see the brand and model of the seal used here:

the seal barely holds the pump and is not moisture-proof
if it rains the tank is contaminated with high humidity causing damage to the fuel system

I hate to say these vendors in their desperation to sell something
They invent any product regardless of quality as it affects the buyer
which in this case is the owner of a DeLorean.

It is incredible in less than 5 days
herko increase the value of the model 131ge pump $ 52 to $ 104
but there are other equally good alternatives:

for only $39.99

So are you saying this pump only provides pressure to 65 PSI or was that only the one from Special T?

[jorge figueroa]

integrated pump sell by specialtauto only develops 65 psi
It should be at least 100 psi

[jorge figueroa]

the idea of integrated fuel pump is good, but the electric pump is simply too weak
the concept developed by dmc uses an electric pump equal to walbro exceeding 100 psi

What will happen if the pump doesn't generate 100psi? Mine has been working okay. I think where there may be an issue, is building up fuel pressure to start the car if it has sat for a couple days. I wonder if I can use my existing housing and install a more powerful pump.

You want the pump to provide more pressure than what your PPR (primary pressure regulator) is set for. That way, if the pump pressure changes a little it won't change your fuel mixture.

Normal PPR pressure is 75 PSI but most I've tested run close to 70 PSI. I shimmed my PPR to get 75 PSI. That is the design value and running less I would assume would limit your high RPM power.

I think there is a specification of the volume of fuel delivered at some PSI.

Sorry to bump an old thread here but the DMCH pump comes with a check valve but these pumps do not. If these are considered cheap alternatives wouldnt a check valve need to be in place when using one of these?

Most of the OEM style pumps have a check valve that is "screwed" on to the top of the pump.
